Constructing artificial solid electrolyte interface on the Zn anode surface is recognized as an appealing method to inhibit zinc dendrites and side reactions, whereas the current techniques are complex and time‐consuming. Here, a robust and zincophilic zinc tungstate (ZnWO4) layer has been in situ constructed on the Zn anode surface (denoted as ZWO@Zn) by an ultrafast chemical solution reaction. Comprehensive characterizations and theoretical calculations demonstrate that the ZWO layer can effectively modulate the interfacial electric field distribution and promote the Zn2+ uniform diffusion, thus facilitating the uniform Zn2+ nucleation and suppressing zinc dendrites. Besides, ZWO layer can prevent direct contact between the Zn/water and increase the hydrogen evolution reaction overpotential to eliminate side reactions. Consequently, the in‐situ constructed ZWO layer facilitates remarkable reversibility in the ZWO@Zn||Ti battery, achieving an impressive Coulombic efficiency of 99.36% under 1.0 mA cm‐2, unprecedented cycling lifespan exceeding 1800 h under 1.0 mA cm‐2 in ZWO@Zn||ZWO@Zn battery, and a steady and reliable operation of the overall ZWO@Zn||VS2 battery. The work provides a simple, low cost, and ultrafast pathway to crafting protective layers for driving advancements in aqueous zinc‐metal batteries.

用于高可逆锌阳极的钨酸锌界面层的原位超快构建

在锌阳极表面构建人工固体电解质界面被认为是抑制锌枝晶和副反应的一种有吸引力的方法，而目前的技术复杂且耗时。在这里，通过超快化学溶液反应在锌阳极表面（表示为 ZWO@Zn）上原位构建了坚固且亲锌的钨酸锌 (ZnWO4) 层。综合表征和理论计算表明，ZWO层可以有效调节界面电场分布，促进Zn2+均匀扩散，从而促进Zn2+均匀成核并抑制锌枝晶。此外，ZWO层可以防止Zn/水之间的直接接触并增加析氢反应过电势以消除副反应。因此，原位构建的ZWO层促进了ZWO@Zn||Ti电池的显着可逆性，在1.0 mA cm-2下实现了令人印象深刻的99.36%的库仑效率，在1.0 mA cm-2下实现了前所未有的超过1800小时的循环寿命。 ZWO@Zn||ZWO@Zn电池，整体ZWO@Zn||VS2电池运行稳定可靠。这项工作提供了一种简单、低成本和超快的途径来制作保护层，以推动水性锌金属电池的进步。
